Unlike most Morning Glories, These bloom in the late evening and close up at the first sign of daylight.

This is the seed pods, as of now I am not sure exactly how many seeds are in each pod or how big each seed is.
Will post picture of dried seed pods, and seeds as soon as they are ready.

These are the seed pods. Each pod has outer layers that are easily peeled away to find another seed casing. Each seed pod has at least 3-4 seeds in each one and each is covered in a soft brown downey silk.
I assume that if left on the vine these would open up and fly thru the air and land where they may sprout out new vines.

This is the tuber from a "small" Ipomoea macrorhiza vine.
This one didn't bloom this year but the mother plant did, I assumed at first glance that this was "several" plants because it had at least 4-5 vines popping up out of the soil. I decided to make a trade with "one" of the little vines and when I started digging....this is what I found!! This is the size of a baseball!! So I just wonder how big the "Mother plants" bulb is?!! I'm sure it has to be at least the size of a grapefruit!!

Love this pale pink bloom, it is a keeper for sure

Seedpod opening, Brevard Conty Florida, February 2004

The buds slowly unwind during the day, opening rapidly after nightfall.

It has a very tropical look when growing up taller plants.
